UE Capability Reporting With Range-Based Dynamic Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UE capability reporting procedures in wireless communication systems do not account for dynamic changes in UE capabilities due to multiple AI/ML models, leading to inefficiencies in network configuration and performance optimization.
Innovation Solution
A method for UE to report capability information based on range information, including values related to CSI, beam, positioning, and model capabilities, allowing dynamic updates and optimizations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If UE capability reporting is performed only once at implementation time, then the reporting procedure is simple and fast, but the capability information becomes outdated when UE capabilities change due to model updates
Solution Approach 1:
The patent transforms the static capability reporting mechanism into a dynamic one by introducing trigger events (model updates, capability changes) that initiate reporting procedures. The UE now can report capability information multiple times throughout its operation lifecycle, not just once at implementation, allowing the network to receive updated capability information when changes occur.
Solution Approach 2:
The patent establishes a feedback loop where the UE monitors its own capability changes and actively reports them to the network. When the UE detects a capability change due to model updates or other factors, it triggers a capability reporting procedure, providing feedback to the network about its current state, enabling the network to adapt configurations accordingly.
2Reliability
If UE capability reporting is performed multiple times to reflect dynamic changes, then the capability information accuracy is improved, but the signaling overhead and network resources increase
Solution Approach 1:
The patent applies partial action by having the UE report only when necessary - specifically when capability changes occur due to model updates or other trigger events. Instead of continuous reporting or reporting at fixed intervals, the system reports capability information partially (only when changed), reducing unnecessary signaling overhead while ensuring the network receives updated information when needed.
Solution Approach 2:
The patent implements preliminary action by having the UE prepare and buffer capability information in advance, so when a trigger event occurs (model update, capability change), the UE can immediately report the updated capability information without delay. This preliminary preparation reduces the response time and signaling overhead compared to generating and transmitting capability information after a trigger event.
3Productivity
If the network configures communication functions based on outdated capability information, then the configuration process is fast and simple, but the communication performance deteriorates
Solution Approach 1:
The patent establishes a feedback mechanism where the UE actively reports capability changes to the network, enabling the network to receive real-time updates about UE capabilities. This feedback loop ensures the network always has current capability information for configuration decisions, maintaining both fast configuration (by using updated information when available) and high performance (by configuring based on accurate capability data).
Solution Approach 2:
The patent transforms the static configuration process into a dynamic one where configuration information is updated in response to capability changes. The network can reconfigure communication functions based on updated capability information received from the UE, allowing the system to adapt configurations dynamically rather than using fixed, potentially outdated configurations.
